6 Appendix: SP-006 Registers

The following Appendix provides the registers and list index for the Layer N SP-006 Pressure monitoring Smart Probe. This
information is intended to aid users who will be making configurations and adjustments to their Layer N SP-006 Pressure
monitoring Smart Probe through the Command Line Interface or other custom interfaces.
6.1

Register Base Addresses

Smart Probe devices share a common platform architecture that provides extensive monitoring and control
capabilities through a set of platform generic registers. These registers may be accessed using I2C based commands
directly to the Smart Probe devices or through a set of Modbus-based registers when using Omega Interface devices.
Refer to the Smart Sensor Device Interface manual for further information.
When powered on, or after a device reset, each Smart Sensor-based device will enumerate 1 or more sensor
instances which are described by the device-specific Sensor Descriptors which include configuration options,
measurement type, and units of measure for the corresponding sensor values. Additional sensor information is
provided in sensor-specific IPSO object descriptions which include extended measurement type, precision, and
tracking of minimum/maximum readings.
Sensors are always enumerated in the order Pressure, Temperature (T), and DIO.
Each enumerated Sensor has a Descriptor Base address location and a Sensor IPSO / Configuration structure address
location based on the sensor mix selected.

6.2.1 Pressure Descriptor

The SP-006 configures the sensors based on the factory device list and user-specified list index. The Sensor
Configuration and Sensor Device fields may be written to provide control of the overall function of the channel
and the signal types used.
